Asking for opinions on "the best" car care products is a lot like asking for opinions on what to put on a pizza. Ten different people can give you ten different answers. I'll assume a few things here -- that your car is still silver (like the pics would suggest
), that your car is well cared for, and that your paint is still original, single-stage. The first step is obviously a good wash! Remove all the dirt and dust laying on the car from winter storage. There are many car wash liquids available that people prefer, but for me, ordinary 99.44% pure Ivory soap works fine
If you need to remove layers of old wax or polish before you start, you can use some Dawn dish detergent for a wash. Second, give the car a once over with a decent claybar and lube (I really endorse the Zaino products and their clay is especially good, but Mothers' and Meguiars and several others also sell claybars and kits) to remove any particles still embedded in the paint surface. It's really not necessary to clay the whole car, but you'd be surprised at how much leftover dirt the clay will remove! Next you can address any scratches and swirl marks present in the paint. Basically, you can either choose to remove them or cover them up. Removing them is where you would use a good machine polish and your new buffer. If your paint is single stage and 30+ years old, it may be a little thin in places, so don't get too aggressive. If they aren't that bad (and lighter colors like silver are very good for hiding imperfections), you can simply try to cover them by laying down a coat of sealant (polish). There are many synthetic polishes on the market today designed for that purpose. Multiple coats will only improve the look. You could also put a coat of carnauba wax over the polish for a "warmer" appearance.
